BALING-PRESS.

Specification of Letters Patent.

Patented Aug. 10, 1909.

To all whom it may concern:

Be it known that I, WILLIAM H. STEWART, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Baling- Presses, of which the following is a specification. 1

My invention relates to improvements in baling-presses; and one of my objects is to provide gearing for imparting positive forward and backward strokes to the plunger so that recourse need not be had to springs, or the expansive force of the material under compression, for retracting the plunger. By

avoiding the necessity of forcing the material several inches beyond the retainers of the press in order to gain its expansive force time will be saved, and by dis ensing with springs the power now require in overcoming their tension and also in obtaining excessive compression of the material will be conserved for thepurposeof compressing said material to the normal density of a bale, and the shock to which the press is subjected by the rebound of the plunger when suddenly retracted by springs and the expanding material, will be avoided.

Another object is to arrange the power mechanism as closely as possible to the plunger in order to avoidundue strain and friction on the working parts of the press.

A further object is to arrange the reach and the plunger-stem in such manner that they will be close to the ground when the press occupies an operative position, so the draft animals can easlly step over sald reach and stem while compressing the materiahl Heretofore,so.far, as I am'aware, in all baling-presses operated by horse-power, the

reach and. the plunger-stem have been arranged so far above the ground as to render it impossible for thehorses, while passing over said reach and plunger, to exert sufficient force to give final compression to a charge of material, hence it has been impracticable to obtain more than three strokes of the plunger to the revolution of the sweep to which the team is hitched.

In order that the invention may be readily understood reference willnow be made to the accompanying drawings, in which Figure 1 represents a broken side elevation of a baling-press provided with my inprovements. Fig. 2 is abroken plan view of same with the baling-case in section, taken on line IIII of Fig. 1.- 1 Fig. 3 is an enlarged broken plan view of the power-end of the press. Fig. 4 is a central vertical section of same Fig. 5 is a on line VV of Fig. 4. Fig. 6 is a front elevation of a casting employed in securing the power mechanism to the front axle of the press. Fig. 7 is a cross-section of the power mechanism taken on line VIP-VII of Fig. 3.

In said drawings, 1 and 2 designate the front and rear axles of the press which are mounted upon carrying-wheels 3 and 4, respectively. V

5 designates a baling-case mounted upon the rear axle and provided with the customary hopper 6 and retainers 7.

8 designates a casting provided with a split-sleeve 9 and a pair of diverging arms 10 which latter are bolted at their rear terminals to the sides of the baling-case.

11 designatesa tubular reach secured at its rear end in sleeve 9 by; means of a machine-screw 12 and a bolt 13 which latter draws the split-sleeve tightly around the rear end of the reach.

14 designates a stationary spur-gear arranged in a horizontal plane and provided at its rear side with a split-sleeve 15 which is drawn tightly around the tubular reach by a bolt 16. The forward portion ofthe spurgear is carried by the upper diverging arms 17 of a casting consisting of said arms, a sleeve 18 through which the forward portion of the tubular reach extends, and a fifthwheel member 19 which rests upon a circularfifth-wheel member 20 provided with segmental .flanges 21 overlapping the ends of member 19. Member 20 has a reinforcement 22 at its underside secured upon axle 1 by means of U-bolts 23. Gear 14 is rightangular in cross-section, as shown in Figs. 4 and 7,

and has internal teeth 24 integral at their lower endswith an annular shoulder 25 arranged in the same horizontal plane with another annular shoulder 26 integral with the inner edge of a horizontally arranged annular web 27 forming the lower portion of gear 14.

'28 designates a driven spur-gear concentrically arranged within gear 14 and provided with external teeth 29 the lower ends of which rest upon shoulder 26 and thus support said driven gear. The smooth portion ill 30 of the periphery of the driven gear is journaled in'shoulder 26to receivethethrust hereinafter described, and thus relieve teeth and thus excludes dust and dirt from space 34. Said cover is journaled in the upper smooth portion 14 of gear 14' and is held in position by clips 38 secured to the upper portion of gear 14 by machine-screws 39.

.Cover 37 is rotated by means of a sweep 40 secured thereto by machine-screws 41 and abutting against the flat sides of bosses 36 to relieve said machine-screws of the shearing strain to which they would otherwise be sub .jected.

42 designates a pitman pivotally secured at its forward end upon a shouldered screw 43', engaging boss 33, and at its rear end to a pin 44 extending through the rear terminal of a plunger-stem 45 and a sleeve 46 secured Y mon axis of gears 14 and 28.

thereto. The plunger consists of said stem 45, which extends through the reach, and a head-block 47 which latter is reciprocably arranged in the baling-case and secured to the forward end of the stem.

When the sweep is rotated a sunandplanet motion is imparted to gear 28 and the pinions 31 which latter rotate upon their own axis and also travel around the com- The rotation 'of' gear 28 will cause the pitman to move back and forth and thus reclprocate the plunger so the latter will successively compress each charge of hay or other material as it is fed into the baling-case from the hopper. The plunger will advance with decreasing speed and increasing power until the pitman reaches the osition shown in Figs. 2 and 3, and as bot the forward and backward strokes are obtained by the ositive gearing above described, springs and the expansive force of the compressed charges will not be required to retract the plunger, hence the latter need only move forward a slight distance beyond the retainers to insure the latter engaging the material when the plunger moves backwardly. Consequently the time and labor usually required in forcing the material several inches beyond the retainers, in order to obtain the expansive force of each charge upon the plunger, and in overcoming the tension of the sprin s will be saved.

The thrust produced by the pitman pulling forwardly upon the plunger will be transmitted to shoulder 26 and the abutting face of gear 28, and asthese abutting surfaces are arranged but a slight distance above the plunger-stem the strain produced when applying power a considerable distance out of ine with the point of use will be avoided, it of course being understood that the closer the power is applied to the major axis of the plunger, the'less strain there will be on said plunger and the gearing.

As the greater portion of the plunger-stem is housed in the tubular reach said stem may be made comparatively light, because the reach will prevent it from buckling under the compressive force exerted thereon during the operation of baling. Another advantage derived in thus arranging said stem resides in the fact that when the machine is placed upon the ground, as shown by dotted line a. in Fig. 1, the draft animals will have no difficulty in stepping over the reach even when compressing a charge, consequently the gearing may be arranged to impart three or more forward strokes to the )Iunger to each revolution of the sweep, as the speed of said plunger need only be governed by the rapidity at which material can be conveniently fed into the baling-case.

Although I have shown the referred construction of my baling- )ress, of course reserve the right to make such changes as properly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters-Patent, is
